DRAW-STRNG BAG.

Application led July 13,1907.

To all whom it may concern:

Be it known that l, Flinn Ti-ronrsor, a citizen of the United State residing at Boston, in the county ol Si elk and State el' lvlassachusetts, have invented certain new and useful Improvements in Draw string Bags, of which the following is a speci-limtion, reference being had thcreinto the aecompanying drawing.

My invention consists ot improvements in draw-string or purse-string bags, and especially such as are used as containers t'or tobacco.

It is designed lirSt, to facilitate the openingl and the closing of 'the bag; second, to do away with the inconvenient knot with which such bags are secured when placed on the market, and third, to provide means whereby the bag may readily be securely closed, and opened.

Figure 1 represents a perspective view oi the usual form or" drawstring tobacco bag when filled, closed, and supplied with my invention. Fig. 2 is an enlarged detail showing a pair of draw-strings, an opening member, and a portion of the mouth oi' the bag. Fig. 3 shows, in full lines, how the bag may be opened; the dotted drawstrings and iingers illustrate how by moving the 'li gers into the dotted positions and drawing upon the strings, the mouth ol' the may be closed. Fig. 4 shows the bag securely closed. Fig. 5 represents a modification.

ln the drawings illustrating the principle of my invention, and the best method of enibodying` that principle, new known to me, are shown a draw-string bag A provided with a pair of draw-strings B, B, and a pair `of wire spiral opening members 1 1/, which 40 by means of hooks 2, 2, that obviously may be closed to preventJ the hooks from being detached from the bag, are secured to the edge portion e, Fig. 2, forming the mouth of the bag. The drawstring, as B, instead of being drawn directly through the passage l), formed in the edge portion, a, ol the bag, as is usually the case, is first drawn through its respective opening member 1, then through one part of said passage, through a hook 2',

Fig. 3, of the other opening member 1, through the other part of said passage b in the opposite edge portion of the bag, and then through and out of the free end of its respective opening member 1. The other draw-string as B is drawn through its opening member 1', the passageway b, the hook Specification of Letters atent.

2,Fig. Zei the opposite' opening member 1, the rest of the passage, and then through and ont oi its rospo.y i .c opening member l. '.he liree end portions oi' earth drawstring are then tied together; the mouth olf the bag is closed; and each draw-string secured to a side oli the bag, as by being pasted or stuck thereto by 1. paper wrapper C, Fig. 1, or other suitable means; the iree ends ol the draw-strings, after beg thus secured, being left free under the lower edge ol the wrapper C, so that each string may be readily grasped, and used to tear through the paper wrapper, and thus, when released, to permit the opening oi the bag.

Users of the purse-string or draw-string tobacco bags are often inconvcnienced in their efforts to untie the usual draw-string bowknot which, for example, during the act of untying, or the act of removing the revenue stamp pasted over the knot and mouth ol the bag, frequently becomes a hard knot. New with my invention, this bowknot is done away with g in liact there is no knot, and no likelihood ol an accidental knot. The exposed portions oi the strings B, B, instead ol being tied in a knot over the mouth of the bag, and stuck down by a revenue stamp, are straight, distant from the mouth, and out of Contact with the stamp, so that there is no possibility that the strings may become accidentally tangled or tied, and the user in convenience/d; all of which is made doubly obvious by another inspection oi Figs. l, 3 and 4. After the draw-strings have become freed, it is often dilticult and exasperating to open the mouth ol the bag, il the bag is not provided with my invention; the fingers of both hands being required to pick it open. Further, when opening such a bag, the user oit-en would like, were it possible, to have one hand free to manipulate a pipe or a cigarette paper, but cannot because both hands are occupied in digging at the closed mouth of the bag. New this annoyance can be avoided by thc use of my invention. To open the bag, the coils 1, 1, Fig. 3 may be grasped, between the thumb and forefinger ot' each hand, and be separated in the way shown in full lines, and the mouth ol the bag opened to the desired extent; the drawstrings gliding freely through the coils, without contacting the ingers. It one desires, he may use his teeth instead of one hand in the above mentioned operation.

It is to be remembered that each drawstring passes through the hook of the opp site coil, so that in opening the bag, should there be tension upon one opening member or coil and one draw-string, the tension Would be borne by the hook, and not by the hook and the edge of the bag, as would be the case did the draw-string not pass through the hook; there Would, therefore, be no tendency to tear that part of the `bag which otherwise Would be subjected to the tension due to the draw-string and the coil.

To close the bag, seize the coils B, B, Fig. 3, alloW the iingers to slip off the free ends of the coils and on to the draw-strings, and then draw the draw-strings in opposite directions, in the manner shown in dotted lines. As in opening the bag, so in closing, the teeth may be used instead of one of the hands.

To have one hand free during either the opening or the closing of the bag, is a great convenience to cigarette smokers. Fun ther, these opening members quickly guide the fingers to the strings.

Users of purse-string tobacco bags seldom re-tie the knot to secure the contents of the bag, because to do so is too much trouble. With my invention, if additional security is desired, this trouble is reduced to a minimum, as Will now appear. After closing the bag, iirst grasp the ends of both draw-strings between the thumb and foreiinger of the right hand. and suspend the bag. This causes the purse-strings and coils to become parallel. Second, With the left hand, grasp the top of the coils, and the strings as they emerge from same, and after drawing the strings tightly through the coils, take several turns around both coils With one or both strings in the right hand the strings lying between the spiral turns Vof the coils, as in Fig. 4. The coils thus become bound together, and at the same time, the contained purse or draw-strings become fixed, and are prevented from loosening. Obviously, the bag may be quickly, easily, and securely closed, and opened.

In Fig. 5, i have shown a modified form of opening members. Instead of being in the form of a Wire spiral, a simple and cheap form of construction, they are made of small tubes.

Having described the construction and operation of my invention and desiring to protect it in the broadest manner legally possible, what I claim is: Y

1. A bag having a pair of draw-strings; a pair of Wire spiral opening members secured to the edge portions of the bag said drawstrings leading through said members.

2. A bag having a pair of draW-strings; a pair of opening members each provided With a hook 3 one draw-string being led through one opening member and the hook of the second member, While the other string is led through the second member and the hook;- of the Vfirst member.

3. A bag having a pair of draw-strings; a pair of opening members each provided With a hook to secure said member to the edge portion of the bag, forming the mouth of the bag 5 one draw string being led through one opening member and the hook of the second member, While the other string is led through the second member and the hook of the lirst member.

4. A bag having a pair of draw-strings; a pair of Wire spirals each provided With a hook, one draw-string being led through one spiral and the hook of the second spiral, While the other draw-string is led through the second spiral, and the hook of the iirst spiral.

5. A bag having pair of draw-strings; a pair oi' Wire spirals, each provided With a hook to secure said Wire spiral to the edge portion or' the bag, forming the mouth of the bag one drav-string being led through one spiral, and the hook of the second spiral, While the other draw-string is led through the second spiral, and the hook of the iirst spiral.

In testimony whereofl affix my signature in presence oi' tWo Witnesses.
